Don Cheadle spilled some information on what we can expect from James Rhodes/War Machine when he returns to the fold for Avengers: Infinity War. The critically acclaimed actor has served as Tony Stark/Iron Man’s (Robert Downey Jr.) best pal in the Marvel Cinematic Universe since Iron Man 2 in 2010 after he took over the role that was first played by Terrence Howard.

Last time we saw him, the military man was in bad shape after his Captain America: Civil War crash. He was paralyzed from the waist down, but some specially designed tech from Stark Industries was seen giving him limited mobility. As it turns out he would need the contraption (or something similar to it) moving forward for his legs to function properly. Hot off Marvel Studios’ impressive D23 Expo panel, Cheadle, together with Mark Ruffalo, who plays Bruce Banner/The Hulk in the MCU, sat down with Good Morning America and shared some new information on Rhodey’s situation when he gets back to action.

The actor revealed that the apparatus somehow makes him bionic — which is reminiscent of James Barnes/The Winter Soldier (Sebastian Stan) who, on the other hand, has a metal arm to replace the one he lost:

“I don’t know that I’d like to use that word, I like fake… It’s an augmentation. It’s somewhat bionic.”

Characters rarely stay dead or suffer permanent, drastic changes in these comic book films — probably because of the nature of its source material — where everyone somehow gets killed and resurrected one way or another. Despite this, knowing that Rhodey will have to be dependent on a machine to be able to walk again is a physical manifestation of the risks of being a superhero. Thus far, we really have only seen Tony’s psychological problems — highlighted in Iron Man 3, when he developed PTSD after his near-death experience in the Battle of New York in Avengers. That said, the arrival of mad titan Thanos (Josh Brolin) is expected to be a universe-changing event. If anything, the D23 exclusive trailer for Avengers: Infinity War is just a taste of what he and the Black Order can do to wreak havoc. Marvel President Kevin Feige has already hinted that several of the MCU’s prinicipal cast members would meet their end in the film — the question is if they’ll stay dead or not.
